s = 25
Step-by-step explanation:
First we go from point (30, 50) to point (-10, 30).
Change in x: -10 - 30 = -40
Change in y: 30 - 50 = -20
Since a change in x of -40 results in a change in y of -20, we divide both changes by 4 to get:
a change of -10 in x results in a change of -5 in y.
Now we go from point (-10, 30) to point (-20, s).
The change in x is -20 - (-10) = -10
The corresponding chang ein y must be -5.
y = 30 - 5 = 25
s = 25
20
10
Two times as much
Is not.
Step-by-step explanation:
Shape 1 formula: 1/3(l)(w)(h) becomes 1/3(4)(3)(5) = 20.
Shape 2 formula: 1/3(1/2 B H1)H2 which becomes 1/3(1/2 x 4 x 5)3 = 10
Shape 1 is twice as much as 10 because 10x2=20
Ali said three times as much which is wrong
